A three-dimensional version of the Periodic System (PS)
of chemical elements is proposed. It is based on the early
works of Russian and French scientists: Mendeleev and de
Chancourtois, while preserving the idea of consistency and
continuity of a number of chemical elements. The resulting
system resembles a “flower” with petals, which are elements
with a certain orbital quantum number. The historical sequence of development of the idea of the spatial representation
of PS chemical elements and the contribution of various authors are considered. D.I. Mendeleev is the true discoverer of
the Periodic Law (PL) precisely because he first saw in him
the Fundamental law of nature, and not just the formal system
of classification of chemical elements that were already long
before him, and the very idea of the periodicity of elements
was known before. In the PL, he felt the unity of the elements
and forces of Nature, and therefore the PS displaying him
should have been a single whole, organically linking empirically isolated elements. According to the logic of the development of science at that time, it is quite natural that the PS could
graphically be represented as the Periodic Table (PT). D.I.
Mendeleev did so, strictly adhering to the principle of consistency and continuity, the first PTs were built. It is safe to say
that the principle of consistency and continuity at that moment
was the main Heuristic principle in the work of a scientist,
which can still be called the principle of integrity.
And he brought overwhelming success and worldwide
recognition to D.I. Mendeleev and PL. Since the PS is a single
organically connected whole, according to the scientist’s belief, any omissions and voids between the elements are absolutely unacceptable. It can be argued that Dmitry Ivanovich
felt that the "infinity" of the PL cannot be adequately (strictly
following the principles of consistency and continuity) expressed in a flat rectangular PT. The scientist foresaw that "...
the system requires a bodily form that allows for convergence in all directions." The spatial spiral shape was first proposed
by the French scientist Alexander Emile de Chancourtois, one
of the predecessors of D.I. Mendeleev in the opening of the
PL. It should be noted that after Shankurtu many prominent
scientists spoke and wrote about the volumetric form of PS.
For example, academician A. Fersman proposed to erect a
monumental monument (in the form of a spatial spiral) PS and
D.I. Mendeleev, and the legendary physicist George Gamow
used the spatial form of PS in his popular books on science.
This spatial form was patented by Roy Alexander. Our model,
in principle, is similar to the models of Gamow and Alexander,
but there are certain differences: the s- and p- elements form
separate independent petals (the previous authors combined
them into one cylinder) and in our version all the petals extend
from the same axis (the lines "growth"). The volumetric model
of PS can be performed in various versions and can be recommended as a student manual.
